Answer: Selena drove more after rest stop than before rest stop by 13.24 hours.
Step-by-step explanation:
Since we have given that
Number of hours Selena takes before rest stop = 1.75 hours
Speed at which she is driving before rest stop = 50.55 miles per hour
Distance = Speed × time
\(Distance= 50.55\times 1.75=88.46\ miles\)
Number of hours Selena takes after rest stop = 2.25 hours
Speed at which she is driving after rest stop = 45.2 miles per hour.
Distance = Speed × time
\(Distance= 45.2\times 2.25=101.7\ miles\)
Selena drove more after rest stop than before rest stop by
\(101.7-88.46\\\\=13.24\ miles\)
Hence, Selena drove more after rest stop than before rest stop by 13.24 hours.
